Large model/runtime files from the original desktop ZIP are intentionally not included in the PyPI source package.

Excluded from PyPI packaging:
- sam2_b.pt
- Houses300.pt
- Houses300.onnx
- Tree50.pt
- yolov8n.pt
- sam2_all_polygons.json
- unins000.exe / unins000.dat
- Windows BAT installer/launcher files

Reason: PyPI has a default single-file upload limit, and model files should be distributed through GitHub Releases, Hugging Face, Zenodo, itch.io, or downloaded into a user runtime cache.

For a local developer install you can still place these files next to mustatil_qt_workspace.py inside the installed package folder, or better adapt Mustatil to read them from an external user data folder.
